AR GAS Piston Retrofit Kit

New from TNW Firearms, Inc.
The GAS piston assembly kit is now available for all barrel lengths with the following barrel diameters (measured 1.5 inches inboard of the site): 0.875, 0.850, or 0.640. This covers most barrels in the 16" barrel range including the M4. The kit includes all the items shown in the picture on the left. Please specify barrel length as Carbine, Mid length or Rifle. Mid length and Rifle size Kits require a modified quad rail forearm that is sold separately starting at $100. Prices may vary depending on the Rifles Barrel length.

TNW has developed a low-pressure, long-stroke gas piston design. Why a long stroke? In order to keep from "hammering" the bolt as the short stroke designs do. We have slowed down the acceleration of the bolt mass and instead accelerated it over a greater distance. The result is less shock forces on the system, longer lasting parts and reliable feeding. It's the difference between unlocking your bolt with a ball peen hammer or accelerating it on a cushion of air!
